i got this error message why
ERROR MESSAGE: SAM/BAM file genome_110616_SN365_A_s_7_seq_GQJ-1.pe.bam is malformed: SAM file doesn't have any read groups defined in the header. The GATK no longer supports SAM files without read groups
i am very new to GATK and i was trying to invoke the readcount command and i got the error above what is read groups.
